Answer:
0.1 m
Explanation:
From the question given above, the following data were obtained:
Mass (m) of ball = 4 Kg
Acceleration due to gravity (g) = 9.8 m/s²
Energy (E) = 4 J
Height (h) =?
The height (h) can be obtained by using the following formula:
E = mgh
4 = 4 × 9.8 × h
4 = 39.2 × h
Divide both side by 39.2
h = 4 / 39.2
h = 0.1 m
Thus, the value of h is 0.1 m
Answer: The answer would be A, D and possible E..
Explanation:
The person will continue breathing of course but, shallow breaths so its not c.
and more waste will travel around the cell because oxygen is use in the cell and the cell distributes waste.. Without air, the cells die and yeahh.. im not very good at explaining sorry^^ but its not b either.
Answer:
Mass does not affect the speed of falling objects,
Explanation:
assuming there is only gravity acting on it. Both bullets will strike the ground at the same time. The horizontal force applied does not affect the downward motion of the bullets -- only gravity and friction (air resistance), which is the same for both bullets.
A.The hiker had an easy, level trail from 11:00-12:00 and was able to travel the fastest during that time period.---> may be because this was indeed fastest stage
b.The hiker got tired and walked the slowest from 1:00-2:00.---> no, because this was not the slowest stage
c.The hiker stopped for lunch from 11:00-12:00 and that slowed him down.---> no because this was the fastest stage
d.The hiker ended up in the same place that he started.---> no, because the hiker walked more toward east than toward west and more toward south than toward north.
Answer: option a)
hope this helps
Answer:
If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.
